Security is a lot tighter in Washington than it used to be. You can't simply wander around the White House in real life, but the new 1600 app from the White House Historical Association lets you scope it out in augmented reality. All you need is a buck. No, it doesn't cost a dollar. You need a real dollar bill as an AR anchor.

Remember back in the early days of Android when it had copy and paste, and the iPhone didn't? Those were strange times. Copy and paste is just something you expect to be able to do now, but there are plenty of places in Android where the text isn't accessible. Microsoft's Clip Layer app aims to change that by binding a universal copy option to the home button.

Brave Software acquired Link Bubble from developer Chris Lacy a few years back, aiming to turn it into a friendlier ad-blocking browser. The name was eventually changed to Brave, but now the owners are reversing course. It's Link Bubble again, and there's a more conventional browser app available called Brave. Yeah, it's kind of a mess.

You needn't wonder any longer how Google is planning to do text input in Daydream VR mode. There's a new Daydream Keyboard app in the Play Store with some very informative screenshots. You can't use it yet, though.

Google's improved quick reply notifications in Android 7.0 can make replying to messages easier, but it's still tedious to manage multiple simultaneous chats. That's doubly true of they're taking place in different apps. Flychat aims to make it easier by bundling all (or at least most) of your messaging apps into floating bubbles. They're chat heads, basically.

Google said Allo would be available at some point during the summer, and it's getting in right under the wire. The new chat application is now official, and it's starting to pop up in the Play Store for download. Don't fret if it's not showing up for you quite yet; we have the APK ready for download.

Google made split-screen multitasking a reality in the Android 7.0 update, and now developers have started fiddling around with the feature. We've already seen Taskbar, which lets you turn on the hidden freeform window mode, and now there's Parallel Windows for Nougat. This app lets you run two copies of the same app in split-screen.

Motorola was the first major smartphone maker to start putting its stock apps in the Play Store. Before that, OEMs would only update those apps as part of an OTA update. It sounds positively barbaric by today's standards. Motorola isn't done yet, though. Just today it added its stock file manager to the Play Store. You won't see much in the way of improvements this time, but who knows what the future could bring?

Do you have 5-10 seconds to spare? Google would like you to spend that time getting something done in its new Crowdsource app. You can apply your human sensibilities to translation and text transcription, and in return you get a sense of satisfaction. Yep, that's it.

Google announced the Duo video chat app (and the messaging app Allo) at Google I/O this year, saying only that we'd see the final release later this summer. Well, here we are. Google Duo is beginning its global rollout right now. It's still showing as "pre-registration" for us right now, but it's finally happening. No sign of Allo yet.
